So I went to update my Jeppesen charts on my G600, all seemed normal, and when turned the G600 on, after going through the whole "Verifying chart data..." bit, it says "Corrupted."
So, I re-updated the data card, same thing.
So, I forced JDM to re-download the chart update (by erasing it's cache), re-updated the card, same thing.
Any ideas?
All the other stuff (NavData, SafeTaxi, Obstacles, Airport Data) updated just fine. So did the GTNs (I don't have Jeppesen charts enabled on the GTNs).
